The Doomed Second Female Lead Is Fighting Monsters by Voicing Her Thoughts

I just want to slack off, so why is there still so much trouble? I'm stuck as the useless Second Miss Cheng. My life is so miserable! My elder sister is so annoying. I'll take her down. The male lead is so plain. I'll take him down, too. Finally, I can slack off, right? Nope, still can't. Oh heavens, you can't bully the queen of slacking off like this! Fine, I'll keep taking them down. As long as I have the spirit of a pig, I'll have the motivation to keep going.
